Thank you, thats a fun one. I particularly like the play on niwa and wani. As for the other premise that modifying the phonetics to accomplish a simplification is based on a narrow view of the reason for retaining kanji literacy... there are important and substantive records for business, legal, and actively functional culture which exist in kanji and require kanji literacy to maintain agreement in society that is one of the differences between Japan and most other places. Who else still operates on contractual obligations from written records of the 17th century? Many current farming leases for large parts of the country are backed with the actual stamped, brush stroke written land records from then, stored at the prefecture on the original papers. Losing the ability to read and write kanji would be detrimental to ongoing cultural stability, and so it will not and should not be entertained by anyone living in that system. People living in a 'for now' mindset are irrelevant to actuality.
